MIXING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 302,420, dated July 22,1884.

v I Application filed December 1, 1883. (No model.)

To aZZ whom it may concern.-

Be it known that we, J OHN MCKEAGE and \VILLIAM \VELLs, of Brooklyn,Kings county, New York, have invented a new and ImprovedMixingdllachine, of which the following is a full, clear, and exactdescription.

lhis invention seeks to provide an effective machine for mixing flour,grain, and similar substances; and the invention consists of the severalcombinations of parts, substantiallyas hereinafter fully set-forth, andpointed out in the claims. I

- Reference is to be had to the accompanying centrally through it fromend to end and from opposite corners, so that the ends of the body standat right angles to the shaft, while the sides of the body are diagonalthereto in all directions, as shown. The shaft B is hollow,

. and is held fast in the uprights G G, and constitutes the feed anddischarge conduit of the apparatus, being provided at one end with thehopper G and formed at the other with the discharge-opening H, andformed withinthe body Awith the outlet-opening I and hopper J, and inthe hollow shaft B areplaced the feeding and discharging worms D D,formed or placed upon the shaft E, which is passed through the shaft Band journaled in the closed ends thereof, and also in the plates orpartitions FF. placed in the hollow shaft B, as

shown in Fig. 1. r i

In operation the material to be mixed-two grades of flour, forexamplewill be fed into,

the hopper G. The body A will be revolved upon the shaft B byabeltcoming from a suit ing from a suitable power passing over the pulley M.cause worm D to convey the material from hopper Gr along the hollowshaft B and disp charge it through opening I into the body A. Inrevolving, the body A, owing to its shape, has a peculiar wabblinggyratory action, and this motion of the body causes the material insideto be tumbled from side to side and end to end of the body, causing itto be thoroughly agitated and mixed. On reaching the discharge end ofthe body A, the material will The revolution of the shaft Ewill belifted by the buckets N, which are secured to the inner sides of thebody A, and emptied from the buckets as they successively reach thepoint immediately above the shaft B into the hopper J, from which itwillbe conveyed along the hollow shaft B to and out of the opening H bythe (liscl1ai-ge-\\-'or1n D in a thoroughly mixed condition.

To prevent any clogging of the material in the hopper G, we provide thehopper with the agitator O, which is given a constant lip-anddownmovement from the eccentric l, secured upon the shaft .15, to whicheccentric the agitator is connected; and in order to break up any lumpsor aggloinerate masses in the material being treated we place within thebody A the-disintegrating-screens Q, against which the material isthrown and through which it must pass. 7

R is an opening, closed by a suitable cap or door, through which anymaterial remaining in the body A may be discharged, or through which thebody A may be fed or charged with material to be mixed in case theautomatic feed is not used; and upon the shafts BE are placed the loosepulleys S 'l, to which the belts may be shipped when it is desired tostop the action of the apparatus without stopping the power.

To the-end and corner of the body A opposite to that to which thecasting L is secured is secured the casting L, which formsa journal forthe body A on shaft B, as will be understood from Fig. l; and suitablecollars may be formed or secured upon the shaftB outside of casting Land pulley S, to prevent all dander of endwise movement of body A uponshaft B.

Constructed in the manner described, it will be seen that the apparatusis self-feeding and self-discharging, so that it is thus adapted forcontinuous operation, and it will also be seen that, owing To the shapeand action of the Patent- 1. In a mixing-machine, the combination, withthe stationary tubular shaft and the wormshaft, ofthe hollow body havingthe subdividing-screens, said body having near one end buckets, and saidtubular shaft having a 110 per outside of the body, and an outlet insidenear one end of the body, and a hopper inside near the opposite end ofthe body, and an out let outside of the body, substantially as and forthe purpose set forth.

2. In a mixing-machine, the Combination, with the right and left handedfeeding-or Worm shaft and the stationary tubular shaft, of the hollowbody having buckets on its inside near one end, and transverselysubdividing screens extending from side .to side of the body, saidtubular shaft having a hopper outside of the body, and adischarge-opening inside of the body near one end, and a hopper insideof the body near the opposite end thereof, and a diseharge'openingoutside of 'the body, substantially as shown and described, and for thepurpose set forth. i JOHN MoKEAGE.
